You can also setup a BI-Beacon using a USB data cable.
(This, however, requires that your user is on a Linux
machine and has the proper permissions (often this
means being part of the dialout user group.)

If you want to go back to default settings, for example if
you forgot the channel key you specified previously, hold
down the FLASH button at least seven seconds. The Beacon
will show a yellow light during this process, and green
when the settings have been reset.

Note

The reset via FLASH is only available in firmware 0.87 and higher.

To reconfigure a Beacon with firmware 0.86 or lower,
reboot it whilst it cannot connect to the router.

E.g by doing any of the following:

Change SSID or password on the router

Turn off the router temporarily

Move the BI-Beacon far away from the router

When you plug it in again, the Beacon will try to connect and
fail. It will then go into setup mode again.
